UNITED STATES PATENT oFFIoE.

A. DE VITZLEBEN, OF \VASHINGTON, DISTRICT OF COLUMBIA.

ENVELOP-RULER.

Speccaton of Letters Patent No. 30,469, dated October 23, 1860.

To all who/m it may conce/r11.:

Be it known that I, ARTHUR DE W'ITZLEBEN, ot the city ot YVashing-ton and District of Columbia, have invented a new and Improved Envelop-Ruler; and I do hereby declare that the following is a full and eXact description thereof, reference being had to the accompanying drawings, and to the letters ot reference marked thereon, in which- Figure l, is a plan vieW of one side of model, and Fig. 2, is a plan view of opposite side.

A, represents a card ot' thick bristol board, but which can be made ot any kind ot' paper, or suitable material. The portion of the card represented by C, is ot a size to fit into one ot the smaller sizes of envelops; that portion represented by D, is intended for an envelop tivo sizes larger than the first; the Whole length of the card represented by E, is intended t'or the largest or Government envelops.

The various portions ot the ruler are furnished vvith ruled lines of sufficient number and at convenient distances apart, for the use of the writer. For instance in the portion of the card represented by C, the lines g, 71., 2'., 1, come into a position convenient to guide thel superscription upon the letter, when the ruler is inserted into the envelop.

The lines g, 71., z', 71;, and the other tivo series, in Fig. l, are ruled to suit business directions, with the lines far apart. The opposite side of the card, shown by Fig. 2, has lines o., Z), o, &c., ruled close together, to suit the hand Writing of ladies, or others Writing small hands.

It it should be required to have the portions C and D of a smaller size than is shovvn in drawings, the card can very easily be diininished, say at the line' 1--2, Fig. 2.

The hole N is made in the card in order to suspend it upon a nail or peg.

The angles or corners of the card are rounded, so that it may not tear the envelop. The operation of lny ruler is as follows: The proper size of the ruler is introduced into the envelop (if the letter is in, then the ruler comes between the envelop and the letter), until the lines a, o, o, &c., are in the proper position, when With ordinary envelops, the lines upon the ruler can be plainly seen through the envelop, thus Serving as a guide in directing the letter.

Having thus fully described my invention, what I claim as new and desire to secure by Letters-Patent, is

A card A, ruled as described, and used as an envelop ruler.
